Next weekend will be the busiest of the 2012 senior football championship campaign with no fewer than eleven games on the hectic programme on Saturday and Sunday.

Saturday features the Donegal-Tyrone Ulster semi-final, plus six All-Ireland Round 1 qualifiers while on Sunday, Croke Park hosts the Leinster semi-finals (Kildare-Meath and Dublin v Wexford) while the qualifier schedule sees Roscommon host Armagh in Dr. Hyde Park and Fermanagh taking on Cavan in Brewster Park.

DONEGAL v TYRONE, Clones (Saturday, 16.30)
They meet for the second successive year and for the 18th time in all in the championship with Tyrone leading 10-6, with one draw. Donegal, the defending Ulster champions, beat Tyrone by 2-6 to 0-9 in last year's semi-final in a game where Colm McFadden (1-1), Dermot Molloy (1-0) and Michael Murphy were their top scorers. Sean Cavanagh (0-2), Stephen O'Neill (0-2) were Tyrone's top scorers.

Donegal are bidding to reach the Ulster final in successive years for the first time since 1992-93. Tyrone last reached the final two years ago where they beat Monaghan.

DUBLIN v WEXFORD, Croke Park (Sunday 16.00)
They meet for the fourth time in five seasons and for the third successive year as Dublin attempt to maintain an excellent run in Leinster which has seen them lose only one of 23 games since the start of the 2005 provincial campaign. That was against Meath (5-9 to 0-13) in the 2010 semi-final. They also drew with Meath in the 2007 quarter-final but, other than those two games, they have won 21 times in Leinster since the start of the 2005 championship.

WEXFORD
Wexford 0-15 Longford 2-9
Wexford 1-13 Longford 0-15 (replay)
